Battery Details
0b00 = V BAT < 2.1V. This condition is also reported in the CHG_DTLS[3:0] as 0b0000
0b01 = The battery is taking longer than expected to charge. This could be due to high system
currents, an old battery, a damaged battery or something else. Charging has suspended and

the charger is in its timer fault mode. This condition is also reported in the CHG_DTLS[3:0] as
0b0110.
0b10 = The battery is OK.
0b11=The battery voltage is greater than the battery overvoltage flag threshold (BATOV),
BATOV is set to a percentage above the V BATREG target as programmed by CHGCV.
Note that this flag is only generated when there is a valid DC input.
Charger Details
0b0000 = Charger is in dead-battery region.
0b0001 = Charger is in prequalification mode.
0b0010 = Charger is in fast-charge constant-current mode.
0b0011 = Charger is in fast-charge constant voltage mode.
0b0100 = Charger is in top-off mode.
0b0101 = Charger is in done mode.
0b0110 = Charger is in timer fault mode.
0b0111 = Charger is in temperature suspend mode, see THM_DTLS[2:0].
0b1000 = Charger is off, DC is invalid and/or charger is disabled.
0b1001 = Charger is in prequalification, fast-charge or top-off modes and is operating with its
thermal loop active (i.e., the junction temperature is greater than the value set by
REGTEMP[1:0].
